5). Set the last frame of the animation to 300 and
move the timeline slider to frame 0.
Figure 13.5 Adding a particle emitter to the scene gets you started, but first, you??™ll need to
scale it down.
4. In the Generator tab of the FX_Emitter panel, change the X, Y, and Z size values
to 35mm, as shown in Figure 13.6.
Figure 13.6 Scale the emitter??™s generator to a tiny 35mm cube to begin creating smoke.

Changing the Generator Size in the
FX_Emitter panel tells the emitter to be
larger or smaller at the point where particles
emerge. Changing the actual size of the
emitter in Layout scales the emitter itself,
not the area of particle generation.
Note
5. In the FX_Emitter panel, click the Motion tab and bring the Velocity Y value to
400mm, as in Figure 13.8. Press the play button in the bottom-right corner of
Layout, and you??™ll see the particles start to stream upward. Note that a negative
velocity value on the Y-axis would send the particle stream downward.
Figure 13.8 Increasing the Velocity value for the Y-axis shoots the particles upward.
Should you accidentally close the FX_Emitter
panel, don??™t worry! Select the emitter item
in Layout and press p to open the Object
Properties panel.
